To all whom it may concern:

Be it known that I, NEWTON subject of the King of Great Britain, residing at Granby, Canada, have invented certain new and useful Improvements in Processes of Manufacturing Rough Texture Brick from Soft Therefor; and I do hereby declare that the following isa full, clear, and exact description of the invention, such as will enable oth'ers(skilled in the art to which it appertains to make and use the same. Y

The present invention pertains to a novel process of manufacturingy rough texture.

brick from soft mud and apparatus for carrying out-fthe process.

The principal object of the invention'is to make possible the manufacture of rough texture brick from the cheap soft mud which is now used-only for common brick. Secondly, this invention enables the manufacturer of soft mud brick to make wire cut, rugged and raked face brick with the ordinary apparatus supplemented by only a few additional parts with a slight addition to the-manufacturing costs.

The process consists essentially in casting in a mould a soft mud slab having the aggregate area of a number of finished bricks. The slab,` while plastic, is cut by a frame into a number of sections of brick size. The cutting frame consists of a rectangular member divided by means of wires or cut-A ting bars into a number of brick-size sections. l The passage of the cutting elementsi into the yslab for separating-the same into a number of bricks imparts to the face of the bricks a rough texture surface accord ing to the nature of the 'cutting element employed.v

The apparatus for car ingout the process includes, first, a mou d for casting'the slab. A cutting base is also provided on which'the slab is deposited from the mould. Finally, 4there is ythe cutting frame which is passed into the' slab while the latter rests base. IThe various parts are provided wit -ap liances for facilitating the entrance of t e cutting elements into the slab and for guiding themovement of theseelements through the slab. The soft v mud is prepared for mouldin and the separate brlcks are finished in t e usual manner. .The additional parts required for A. Mavim,

Province of Quebec,

cutting' base;

carrying out this process are of simple constructionA and add very littleto the cost of the present soft mud 'manufacturing equip' ment.

The invention is fully disclosed 'in4 the i following description and in the accom-v panying drawings in which; l

Figure 9 is an end view, partly in section, of the cuttin base; and

Figure 10 is a ragmentary longitudinal section of the' mould.

Reference to these views will now be made by use ofA like characters which are employed to designate corresponding -parts A s ab of soft mud having the aggregate area of a given number of'bricks, prefern ably six, is formed in a mould such that shown in-Figure 5. 'The bottom 1 of the mould is surrounded by side walls "2 and' end walls 3 forming the cavity for casting. The bottom ofthe mould carries a number of plates 4 corresponding in number to the bricks that will be made from the slab, and

mark or the like on each such brick.

'A number of these :moulds are filled in al longitudinal section of the 'these plates are adapted to impress a trade .cutting frame through the slab imparts a rangement to the bricks that will be formed from the slab. Spaces 9 are retained between the sections 8, and metallic plates 10 are secured to the sections with their edges turned down into the spaces as indicated by the numeral 11 in Figure 8. The longitudinal space 9 is .enlarged as at 12 at lts ends to permit entrance of the hands of the operator in order to grip the handle straps 13- bridged across the enlargement 12 and move the base as required. Guide fingers 14 are secured to the edges of the base for the purpose'pointed out below.

The mould is next carried from the soft mud brick machine, emptied on the base, and lifted from the slab deposited on the base as illustrated in Figure 1.

The next operation is to cut the slab into a number of separate bricks by means of a cutting frame. This device consists of rectangular members 16, as shown in Figure 2, havin cutting rakes 17 stretched between the sides and ends thereof, dividing the interior of the frame into a number of bricksize sections. .The sides of the members 16 are provided with guide notches 18 which receive the fingers 14 and thus determine the path of travel which the frame takes while being pressed into the slab. The cutting frame carries a number of coil springs 19 between which are provided spring clips 20. When the frame reaches its lowermost position, the coil springs 19 are compressed and the spring clips 20 lock against the handle straps 13. This assembly, comprising the cutting base, slab and cutting frame,

is now inverted so that the cutting base lies onthe pallet 6 as shown in Figure 3. It is now necessary to remove the cutting base, and the clips 2O are pressed inwardly to remove it from the cutting frame. The base is now lifted as shown in Figure 3, leaving only the cutting frame and the slab on the pallet holder. Finally, the cutting frame is withdrawn as illustrated in Figure 4, leaving the separate bricks on the allet holder. The bricks are then removed or drying and finishing in the usualvmanner.

The passage of the rake bars 17 yof the raked face to the brick, resembling the appearance of a brick made bythe stiff mud process. Instead of the rake bars, the cutting frame may be provided with similarly disposed wires 21 as shown in Figure 7. This frame is used in the manner already described and forms a wire cut face also resembling that produced on a stii' mud brick. It is to be understood that, the cutting elements of the cutting frame may have various forms for the purpose of imparting different kinds of'faces to the brick. The essential-feature of the invention remains the same, namely, that a. number of rough texture faced bricks are formed by cuttlng a soft mud slab.

Whlle a specific embodiment of the 1nvention has been illustrated and described, it is to be understood that various alterations in the details of construction may be made Without departing from the spirit of the invention as indicated by the appended claims.

I-Iaving thus fully described the invention, what I claim as new an'd desire to protect by Letters Patent is:

1. A process of manufacturing rough texture brick consisting in casting a slab of soft mud brick material in an undivided mould, depositing said slab on a base, inserting in said slab, while'plastic, a cutting frame which divides the slab into a plurality of bricks having a rough texture surface, inverting the base, slab and frame collectively, and successively withdrawing said base and frame from the slab.

2. An apparatus for manufacturing rough texture brick from soft mud comprising an undivided mould adapted to form a slab of brick material having the aggregate area of aplurality of bricks, and a cutting frame having substantially the internal dimensions of the mould and divided into a plurality of brick-size sections.

3. An apparatus for manufacturing rough texture brick from soft mud comprising an undivided mould adapted to form a slab of brick material having the aggregate area of a plurality of bricks, and a cutting frame having substantially the internal dimensions of the mould, and a plurality of cutting elements dividing the frame into brick-size sections. f

4:. An apparatus for manufacturing rough texture brick from soft mud comprising an undivided mould adapted to form a slab of brick material having the aggregate areaof a plurality of bricks, a cutting base adapted to receive the contents of said mould, and a cutting frame having substantially the internal dimensions of the mould and divided into a plurality of brick-size sections.

5, An apparatus for manufacturing rough texture brick from soft mud comprising an undivided mould adapted to/form a slab of brick material having the aggregate area of a lurality of bricks, a cutting base adapted to receive thecontents of said mould, and a cutting frame having substantially the internal dimensions of the mould, and a plurality of cutting elements dividing the frame into brick-size sections. l,

In witness whereof I have hereunto set my hand.
